Wiring the Power Inputs
1. Insert the positive and negative wires into the
V+ and V- contact on the terminal block connector.
2. Tighten the wire-clamp screws to prevent the DC
wires from being loosened. See Figure-2
Notes: The recommended working voltage is DC24V (DC12~ 48V).
Wiring the Relay Output
The relay output alarm contacts are in the middle
of the terminal block connector as shown in the
figure below.
By inserting the wires and set the DIP switch of the
respective Port Alarm to "ON", relay output alarm will
detect any port failures, and form a short circuit.
The alarm relay output is "Normal Open". See, Figure -3.
Wiring the Earth Ground
In an industrial environment, there might have
a lot of devices that generate electromagnetic
noise, such as AC motors, electric welding
machine, power generator. These devices will
generate electric noise or surges that might
disturb communications. To prevent those noises,
the switch should be well earthed.
In the figure- shows how to make connection. See, Figure -4.
